Abstract
A pixel circuit driving method comprising: receiving an image signal, wherein the image signal comprises multiple pixel values; using a first lookup table to obtain multiple first voltage data corresponding to the multiple pixel values in a first original frame; using a second lookup table to generate a multiple first voltage combinations according to the multiple first voltage data, wherein each of the multiple first voltage combinations comprises multiple update voltages, and the multiple first voltage combinations correspond to a multiple first update frames; generating the multiple update voltages to multiple driving multiplexing circuits according to each of the multiple first voltage combinations by multiple power generating circuits; and using the multiple update voltages as multiple driving voltages to provided to multiple pixel circuits by the multiple power generating circuits.
